The UK Inheritance Tax is the tax levied on the estate of a deceased person. It applies to estates that exceed the tax-free threshold of £325,000, at a rate of 40 percent. Thankfully, a number of exemptions and allowances can help a UK expat reduce their IHT liability. Read on to find out more.
Top 2 Strategies to Reduce the Potential Inheritance Tax Liabilities for UK Expats
Exemptions
If all the wealth over the Inheritance Tax threshold is left to the spouse or civil partner of the deceased person, then no tax is due. Moreover, the IHT threshold can be as high as £1 million per couple if the family home is left to a child, foster child, stepchild or grandchild, provided that the family home is left to direct descendants and any unused nil-rate band and residence nil-rate band can be transferred to the surviving spouse or civil partner. Likewise, if all assets above the Inheritance Tax threshold are left to a charity or a community amateur sports club, then no IHT is due.
Change Your Domicile Status
If you are classified as a long-term UK resident (broadly, UK tax-resident for at least 10 of the previous 20 tax years), all your worldwide assets are liable to UK Inheritance Tax. Prior to 6 April 2025, this was determined by UK-domiciled status, but the system has since moved to a residence-based test.
The UK government recognises domicile status based on three contexts:
Domicile of Origin – A Child takes their father or single mother’s domicile of origin, which is not necessarily the country where the child is born
Domicile of Dependence – It applies to women married before 1974, children and mentally incapable individuals
Domicile of Choice – It can be obtained by permanently relocating to another country
One way to avoid Inheritance Tax as a UK expat is to change your domicile status to another country. To establish a new domicile of choice, you must be physically present in the new country, be a tax resident there, and intend to stay permanently with no plans to return to the United Kingdom. Even mentioning in your will that you want to be buried in the UK will work against you. The goal is to cut as many ties with the United Kingdom as possible.
For exemption and mitigation of the UK IHT, the length of time you remain within scope after leaving the UK depends on how long you were previously UK-resident — from as few as three years to as many as ten years under the long-term UK resident rules that apply from 6 April 2025. From 6 April 2025, the deemed domicile rules were replaced by a new long-term UK resident (LTR) test. You are now treated as a long-term UK resident for Inheritance Tax purposes if you have been UK tax-resident for at least 10 of the previous 20 tax years. If you leave the UK, you may remain within the scope of IHT for a further 3 to 10 years depending on how long you were previously UK-resident.
Changing domicile status to avoid UK IHT is genuinely difficult, since IHT is a significant source of income for the UK government. You’ll need to demonstrate that you have no intention of returning to the United Kingdom. Some steps that might help the process include:
Severing ties with all social organisations of the UK and joining new ones in your country of residence
Relinquishing your British passport
Selling all your UK-based properties and purchasing real estate in your country of residence
Closing all your UK bank accounts
